Document Summary
Anatomical variation determines athleticism and injury resilience. Purpose of the transverse processes is to widen out the stability. Facet joints: control twist, can angle at very different angles. Having a big spine wont allow you to hit a golf ball (eg. nfl linebackers) The angle at which the transverse process is at changes the way it glides (cid:1) (cid:1) (cid:1) (cid:1) At psis medially is the spinous process of l5. L4/l5 disc: belt line, mid a-p. Mechanism to get degenerative disc is flexing the lumbar spine: people big huge bellys that hang over the belt don"t suffer from this. The normal person has the fulcrum at 55% form the anterior posterior (ap) distance (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Common sites of fracture: pars bone that holds the facet joint on, labrum is the disc above the vertebrae (mva, heavy bending, spinous process (people break this in life or death situations)
